Abstract (en)
[origin: US2014054270A1] In an electrical distribution system having an arc management system for removal of arcing voltage from feeder circuits triggered at least in part by light signals, a secondary optical detector monitors a downstream branch circuit breaker in the feeder circuit compartment to produce an optical signal for arc detection more accurately reflecting the possibility of an arcing fault.
